Tooll whomit may concern:

I Be it known that I, FREDRICH GEBHARDT,

a. citizen of the United States, residing at Alliance, in the county of Stark and State of Ohio, have invented new and USO/fill Imowing is a specification.

This invention relates car trucks and itsobjcct is to construct the truck of comparatively fewparts and to connect the parts in a simple manner so that they may be readily assembled and taken apart. I Another object of the invention is to provide for a lateral adjustment .of the truck bolster relative to the truck frame to relieve the truck to a very large extent from the usual strains in service and thereby decrease the rails and on the flanges of the wheels. And a further object of the invention is to constructthe truck so that the bolster may be easilv and quickly removed througheither side frame.

In the accompanying drawings Figure 1 is a top plan view of a truck embodying my invention without the bolster. tail view of one of the removable guides for the channel plate connecting the side frames to the truck. Fig. 3 is a sectional view on. the line 33-- of Fig. 1, and showing one of of the truck in elevation. Fig. 4 is an'enlarged sectional view on the 1. Fig. 5 is an enlarged sectional view on the line 55 of Fig. 3. Fig. 6 is a detail perspective view of one end of the channel connecting plate. Fig. 7 is a sectional view on the line 7-7; of Fig. 1, the

bolster and some of the other parts being showing the tie strap. View on the line 1()1O of Fig.3. Fig. 11 is omitted. Fig. line 8 -8 of Fig. plan view of 8 1s asectional view on the 7. Fig. 9 is a detail bottom a portion of one side frame and Fig. 10 is a sectional on the line l111 of Fig. 10. are plan views of the bearing a sectional view Figs. 12 and 13 plates, I y g Referring to the drawings, the side frames 2, the lower arch 3 and the truck co umns 4 (Fig. 3). Each side frame is provided at its ends'with projections 6 having guide lugs 7 on the underside thereof, to receive the journal boxes 8. At the bottom of the side rovernents in Car-Trucks, of which the fol to improvements in Fig. 2 is a de-- frame, between its ends, there is a seat 9 formed between two guides 10 (Fig. 9) for the tie stra cured in through t tie strap, at the endsthereof, and through the projections 6 of the side frame.

The guide grooves extend downward below the lower wall of the opening 16 to re ceive the lower ends of the guide bolts and so that the guide bolts will be securely held at their lower ends as well as at their upper ends in an upright position. I vide the side frame with a, ateral opening 32 extending'from the lower end of the guide groove to the front or side of the frame so that a tool or instrument of any suitable kind the guide bolt to loosen it in event that it becomes rusty or stuck and facilitate its removal. The lower end of the guide bolt may be beveled or otherwise shaped and fitted to ermit a chisel or other tool or instrument to lie driven thereunder.

The side frames are movable channel plate channel plate is secured removable guides 14 (Fig. 2) which may be made in the form of bolts and are seated in guide grooves 15 in the tru columns. The guides 14 project into the opening 16 between the truck columns and-the channel plate 13 is provided with recesses 17 to receive said guides. In addition to this means for securing the channel plate to the side frames I may fasten the plate to the frame by bolts 18 (Fig. 5) and I may also provide the channel plate with ears 1.) (Fig. 6) :iniii'. bolt them to lugs Ed on the side frame (Fig. 7). Either the bolts 13 or the cars 19 or both maybe used. or they may be omitted. entirely, as desired] ()1- the channel plate may terminate at the dotted line 21, at each end thereof,- (Fig. 6), in which case thewlate would be secured to the side frames by olts passing through the cars 1!).

I may use any suitable holster in my improved truck and in the drawings I have shown a cast bolster 22. (Fig. 3) which is arranged betwecn the truck columns and supported on the. springs .23. The bolster is provided with recesses 24 (Fig. 4) to receive the removable guides 14. The springs 23 connected by a re 13 (Fig. 6) and this are mounted on a bearing fitting between the refer also toproto the side frames by 11. The journal boxes are se- 1pace by bolts 12 which. extend may be inserted therein and forced beneath cpiartly I the removable guides '14. "Ihc 10.

' on-the upper member truck columns and resting upon the connect ing. plate 13. Y upper member The upper member-(Fig. 12) has aronvex surface and the lower member (Fig. 12-? has a concave surface 26 to receive the vex'surface onthe'upper member. Both members are notched at 27,27 to receive upper member is provided atits corners with studs 28 and the lower member 26 is provided at its corners with recesses 29 to receive the-studs The notches 2? in the upper member are longer than the notches'27 in the lower member and the re cesses 29 in the lower member are somewhat larger than the studs 28' on the upper member', so that. the upper member, on which the springs 23 i'es't, may 'move rotatively and universally on thelower member. The concavi'i-couvex bearing provides a firm support for the springs and also an adjustablesupport whereby the bolster, which rests on the springs, may adjust itself, to relieve'istrams on the truck. The movement of the upper incmlfier on the lower member is limited by the studs 38 engagingthe recesses 29 and also bythe end walls of the slots 2,7 engaging the removable guides Whenever the truckbinds on the traclrfor any reason the.

bolster will adjust; itself automatically and release the strain thereby decreasing the friction and wear on the rails and-the flanges of, the wheels. This manner of supporting the bolster at" its ends may be used in 'conn ection with truck frames of other desription with equallysatisfactory results.

The guides 14 are loosely inserted in place in the side frames and are provided with heads 14; which are preferably located in recesses 30 in the side frames (Fig. 4)." These guides may be kept from working up by any suitable means such as the transverse pins 31. passing through the, walls of the rcccsses30. The guides 14 may be madc'of any desired transverse shape and diameter and the grooves 15 in' the truck columns and also the "relcessesin the connecting plate 13; the spring bearing and the bolster are made of a shape and size to accommodatethese guides.

, My improved truck is composed of a comparatively few parts, the side frames each consisting inits principalpart' of a steel cast ing. The parts are so arranged and constructed and connected that they can be readily and uickly assembled or taken apart, The tie strap is held between the guides 9 on the frame and is secured at its ends only which secure the journal boxes in place. The journal boxes can be easily removed from the frame by loosening or detaching these bolts. The side frames are held together by the eonnectingplate which may be secured to the frames by the guides or by the This bearing consists of an 25 anda lower member '26.

arranged in said to the frame by the same bolts,-

guides and the bolts as heretofore described ll: by theguides 'only, the plate canbeeasily disconnected from the frames by removing the guides; ifthcubolts aroused they must, of course,.be removed also.

These removable'guirle's constitute avery simple and effective means for securing the connecting plate, the spring the side frames of the truck. The truck hanger brackets 33 maybe cast integral bearings and the bolster in with the side frames or they may be bolted Y thereto as desired.
